Pg. 09 Four-Sided Caltrops should use a standard action instead. Creating an encounter lasting zone that applies a save ends effect as a minor action for only 30 gp seems a little too cheap and a little too good. It could be made Rare to avoid loading on them.

Pg. 09 Shape of the Multiverse power's triggershould be changed to: "You or one ally within 10 squares of you makes an attack roll, skill check, or saving throw and dislikesthe result."

Pg. 09 Raven Tens utility power is missing an action type.

Pg. 32 Ysrilla Lightstep's Scimitar attack power is missing a critical hit entry being high crit.
